+ - The first time I ran this I got a missing dependency error because there had been a minor version update recently. The dependency error was fixed a few hours later. Right after that, the official version of 4.2 was released. To see the original error error, see the edit from 01:48:39 09/13/12.

+ - The notes at the URL above mention adding lines to xorg.conf for mouse integration, but I didn't see an xorg.conf in /etc/X11 or in /etc so I skipped this step for now.

+ - The notes also mentioned creating a file for HAL users or copying it, but I didn't see a file at /usr/local/share/hal/fdi/policy/10osvendor/90-vboxguest.fdi so I am skipping this step for the moment.

+ - Restart.

+ - I just noticed that the lines had already been added to /etc/rc.conf, so I removed the extra ones that I had added.
